C++ Short-Circuit Operators_Increment and Decrement

Comment

Example 5-24. Overloading the increment operator
enum status { stopped, running, waiting };
status& operator++(status& s) { // Prefix
 if (s != waiting)
 s = status(s + 1);
 return s;
}
status operator++(status& s, int) { // Postfix
 status rtn = s;
 ++s;
 return rtn;
}
int main( )
{
 status s(stopped);
 ++s; // Calls operator++(s);
 s++; // Calls operator++(s, 0);
}

	int b, a, e, d, c, f;
    int num = 57;
    cout << "The number is " << num << endl;

    b = ++num;
    a = ++num;
    e = a + 1;
    cout << "After post increment by 1, the number is " << b << endl;
    cout << "After pre increment by 1, the number is " << a << endl;
    cout << "After increasing by 1, the number is " << e << endl;

    d = --e;
    c = --e;
    f = c - 1;
    cout << "After post decrement by 1, the number is " << d << endl;
    cout << "After pre decrement by 1, the number is " << c << endl;
    cout << "After decreasing by 1, the number is " << f << endl;
